From the cardback:

The bounty hunter Jango Fett is a shrewd mercenary mysteriously linked to the growing Separatist army and the unexplained assassination attempts on Senator Amidala. Armed with dual pistols and a jet backpack, he is always prepared for dangerous confrontations. Jango is equally as dangerous in space as he pilots his modified starship, Slave I, to capture or destroy anything that gets in the way.
